I am not an -IT pro and I would like to ask for help.
This is the configuration of my Home lab server running on Proxmox.
- VM01 - Ubuntu server 22.04 + NGINX Proxy server in docker
- VM02 - Ubuntu server 22.04 + Nextcloud SNAP 24.0.6snap1 + Collabora Online Code server in docker on port 9980
There are 2 subdomains
- nextcloud.mydomain.sk - Nextcloud SNAP (has its own SSL certificate but it goes through NGINX).
- collabora.mydomain.sk - Coolabora docker proxied via NGINX - I used this tutorial for installation Collabora Online (Nextcloud Office) Code Server Docker Container Installation inkl. Reverse Proxy - YouTube
Written tutorial for it - Collabora Online (Nextcloud Office) Code Server Docker Container Installation inkl. Reverse Proxy - apfelcast
The Nextcloud SNAP subdomain works fine. The Collabora Online server is also reachable with the status OK (as shown in the tutorial).
I installed the Nextcloud office app.
Here comes my issue.
Nextcloud office app settings - Use your own server
I put it there - https://collabora.mydomain.sk
After 20 sec I receive -
Could not establish connection to the Collabora Online server.
I fight with the issue for more than a week.
What am I missing?
Could you be so kind and would you help me solve the issue?
Thank you for your answer.
